    Default A matter of trust, Mr DB?

    haha. okay basically, I have an ampro dry box that I use alongside my DB dry cabi.

    I set my ampro box to 40~45% RH, and for 'feeling' sake, I often note that the air in the box is rather cool and dry ( expected ). Like air-con like that. the box uses analog RH meter.

    I calibrate my cabinet to also 40~45%, as shown on its digital readout meter. I tell you, the calibration is very tedious, but its quite fun...

    The thing is, everytime I rush my hand into the cabi when I open it, the air is not as cooling as my box! same RH, how come....?

    I have taken into consideration the difference in volumes for the both. But the level of 'coolness' of the air inside should be proportional with volume, no? (lower RH, more cool)



    how? To trust the digital meter or not? It seems to lie.

    Its physics. BTW, your digital meter will never be as accurate as your analog meter, physics again.

    Everything u see and feel in this world is analog, temperature, humidity, etc. Some engineers invent electronic circuits to convert all these analog measurement to digital data, to make it easier to read, the conversion from analog to digital data use some formula, and it is not 100% accurate.

    If you didn't calibrate the analog.... its still not accurate...
